Relieve valve on top of hydro pump stuck, plunger might be stuck down.
312 no forward drive
my 312 was driving fine in forward and reverse, then the engine threw a rod, tractor down for 2 months, put in rebuild engine and no forward drive, reverse works fine, fluid is full, valve is backed all the way off, linkage that I can see seems to be moving correctly, one other thing it cannot be pushed forward wheels slide, pushes backward fine, beats me, any ideas greatly appreciated, thanks
